After transmigrating into a high-martial world as the only son of a city lord suffering from a terminal illness, Bai Hua should have been a winner from birth.
Unfortunately, the renowned doctor Hua Tuo descends from the heavens and predicts his death: he won't live to see nineteen.
In a world where people awaken their guardian spirits at eighteen, he drags his frail body onto the awakening platform.
His father possesses the strongest Bai Qi guardian spirit alive, and everyone believes Bai Hua's S-rank bloodline is destined to go to waste.
As the ceremony begins, the sky splits open with two beams of golden light.
Two legendary brothers from the Tang Dynasty, missing for a thousand years, appear from beyond the heavens. "Who but him is worthy of inheriting this Dao of Yin and Yang and all living beings?"
The world is stunned: a priest and an assassin? A bizarre mage?
Even more astonishing, his two guardian spirits can combine Yin and Yang, letting him defeat enemies of higher ranks!
